[VOIPSEC] An issue of trust?

I have contributed several times on this mailing list about the need for
identity-based communications that includes a cryptographic identity on
every packet.  The opensource architecture is called the Secure Mobile
Architecture (SMA) and is published in The Open Group
(http://www.opengroup.org/bookstore/catalog/select.tpl?text=secure+mobil
e+arch). 

Having published a VOIP architecture for Boeing in 2000, I have thought
a lot about the Internet can and should handle telephony.  It is a
contention of mine that most of us will eventually almost never need,
nor use, an E.164 address.  We will, however, use a web-based directory
or SIP URL to access Internet telephony addresses.  You will find it
much easier and more convenient, in the near future, to use these
sources of addresses than to use or look up a number.  The key is the
underlying assumption (that is in contention here) is that you will
actually be getting the party that you need to talk to and not be
spoofed by other IP or MAC addresses.  The protection that you get from
an architecture that uses a cryptographic identity on every packet, the
Host Identity Protocol (HIP), a virtual directory to store and reference
the addresses, and possibly even location,  make for a complete package
of trust using authentication, authorization, and protection of IP
telephony.

Sorry to intrude...
I guess the big question here is, is VoIP Internet Telephony or
Telephony on the Internet?

There are 2 recognised standards 1 administered by Internet people
(IETF) and based on existing Internet technologies to do telephony and 1
administered by the telephony people (ITU) based on telephony to be
carried over the Internet.  You can successfully argue it both ways
however it appears the regulators have chosen to look at it one way and
a large pert of the industry to look at it another.
